Subject Re: [PROPOSAL] Create and provide karaf-boot plugin
Date Tue, 28 Apr 2015 05:30:30 GMT

yes, right now you already can update lib folder or modify the 

The proposal is not a new way to deploy feature (I think we already 
provide good ways to do that): it's more to find a way to have "ignition 
key turn" bootstrapping Karaf and application.

On a local branch, I worked on some new goals for the karaf-maven-plugin, especially: karaf:run
to easily bootstrap and start a Karaf instance +1 karaf:deploy to upload (scp) the project
artifact (or a given artifact) in the deploy folder or the system folder (respecting the maven
structure) +1 we could also add sftp and http/https upload, with the help of the maven http
servlet i've added in 4.x karaf:client to connect to a running Karaf instance and execute
commands +1, i suppose we'd need interactive and scripted, like the bin/client script, right
? I would like to add a new plugin (more than a new goal): karaf-boot-maven-plugin with the
boot goal. The purpose is easily: 1/ in the end user code module, build a karaf custom distribution
including karaf standard distribution and the end user built application 2/ be able to easily
include test with pax-exam 3/ provide a ready to run artifact 4/ provide a
> way to specify profiles or features to include in the distribution It's just an idea
for now. The purpose is to provide a ready to run Karaf container like users does with spring-boot.
So it would create the distribution, same as the install-kars / assembly goal, then use the
karaf:run goal ? The only step than the assembly / run / archive goals can't do is the tests,
but I'm not completely sure to understand this part... It looks more like an archetype than
a plugin to me ? Or do I miss something ? Thoughts ? Regards JB -- Jean-Baptiste Onofré jbonofre@apache.org
